+/* 
+*** Source: LeetCode ***
+
+Given an integer x, return true if x is a 
+palindrome
+, and false otherwise.
+
+* Example 1:
+
+Input: x = 121
+Output: true
+> Explanation: 121 reads as 121 from left to right and from right to left.
+
+* Example 2:
+
+Input: x = -121
+Output: false
+
+> Explanation: From left to right, it reads -121. 
+> From right to left, it becomes 121-. Therefore it is not a palindrome.
+> Example 3:
+
+Input: x = 10
+Output: false
+
+> Explanation: Reads 01 from right to left. Therefore it is not a palindrome.
